8 Claims. (Cl. 20-64) This invention relates to Weatherstrippingconstructions and more particularly to Weatherstripping adapted for usein insulating doors and other similar closure structures.

The primary object of this invention is to provide a Weatherstrippingconstruction which will elfectively shield a house or other buildingfrom penetration by air currents, dust and the like, which will closeany interstices between a door and the door frame and which willeffectively provide a seal at the bottom of a door.

Still further objects of the invention reside in the provision of aWeatherstripping construction that is strong and durable, relativelyeasy to install by eliminating the necessity for doors of specialconstruction or the necessity of having special tongues or groovesformed in the edges of the door, which is relatively inexpensive tomanufacture and which is relatively easy to install by any home ownerwithout requiring special instruction or training.

These, together with the various ancillary objects and features of theinvention which will become apparent when the following descriptionproceeds, are attained by this Weatherstrip construction, a preferredembodiment of which has been illustrated in the accompanying drawings,by way of example only, wherein:

Figure 1 is a sectional detailed view illustrating the construction ofthe Weatherstripping as used at the bottom edge of a door;

Figure 2 is a sectional detail view similar to that of Figure l butshowing the door in an opened position;

Figure 3 is a sectional detail view illustrating the construction of thevertical Weatherstripping members adapted to be secured to the doorframe;

Figure 4 is a perspective view of the sheet having the resilient stripattached thereto which is adapted to be pivotally mounted below thebottom edge of a door; and

Figure 5 is a perspective view of Weatherstripping which is adapted tobe secured to the door frame.

With continuing reference to the accompanying drawings wherein likereference numerals designate similar parts throughout the various views,reference numeral generally designates a door to which theWeatherstripping comprising the present invention is adapted to besecured to insulate the building for which the door forms a closure fromair currents, dust and the like. To the bottom of the door 10 there issecured a frame strip 12 which is held in position by means of screws 14or other suitable fasteners. The frame strip 12 has a downwardlydepending flange 16. Positioned against the frame strip 12 is an upperwedge 18 of resilient material such as rubber. Directly below the upperwedge 18 there is positioned a sheet 20 having an angularly downwardlyextending portion 22 forming an actuating flange which terminates in aportion 24 extending substantially parallel to the main part of thesheet 20. Secured immediately below the sheet 20 is a lower wedge 26 ofsuitable resilient material which has its thickest portion thereof at apoint remote from the actuating flange 22 and opposite from the positionof the thicker portion of the wedge 18. Below the lower wedge 26 thereis provided a plate 28. Screws 30 extend upwardly through the plate 28,the lower wedge 26, the sheet 20, the upper wedge 18, and the framestrip 12 to hold these elements in an assembled position. It is to benoted that the apertures 32 through the sheet 20 are of larger size thanthe shank of the fasteners 30 thus permitting pivoting movement of thesheet 20 relative to the door 10. The edge of the sheet 20 remote fromthe ice actuating flange 22 has bonded thereto a strip of resilientmaterial 34 such as rubber or the like.

Extending across the opening for which the door 10 forms a closure is adoor sill or threshold piece 36. By means of any suitable fasteners orthe like a cam plate 38 having an angularly extending cam surface 40 isaflixed on the door sill 36. The cam plate 38 is adapted to be engagedby the actuating flange 22 when the door is being closed which will urgethe sheet 20 to pivot. This will cause the thicker portions of thewedges 18 and 26 to become compressed as can be best seen in Figure 1.When the door becomes fully closed the portion 24 will rest on the topof the cam plate 36 and the resilient strip 34 will be held against thecam plate 40 forming a seal. Likewise, the sheet 20 will be held againstthe upper wedge 18 forming a seal therewith. This will prevent passageof any air currents, dust, and the like through the interstices thatwould normally exist between the door 10 and the door sill 36. When thedoor is opened the wedges 18 and 26 will be free to return to theirnormal shape thus urging the sheet 20 to return to its initial position.It is to be noted that the flange 16 will act as a guard for the sheet20 preventing any foreign matter from accidentally forcing its waybetween the sheet 20 and the frame strip 12. v

Referring now to the Weatherstrip construction as is shown in Figures 3and 5 it will be noted that the door frame 50 has aflixed thereto bymeans of screws 52 or other suitable fasteners one flange 54 of anangular Weatherstripping member the other flange 56 thereof extending atan acute angle relative to the flange 54. The

flange 56 is further bent as at 58 to form a portion substantiallyparallel with the flange 54. A resilient strip 60 is bonded to the innersurfaces of the flange 56 and the flange portion 58. When the door 10 isclosed it will abut against the resilient strip 60. Since the flangeportion 56 extends at an angle relative to the flange 54 and the frame50 and since it is formed of a metallic material of resilient nature aneffective seal will be formed between the resilient strip 60 and thedoor 10. The fasteners 52 extend through suitable apertures 62 in theflange 54, means being provided to countersink the heads of the screwsor fasteners 52. The angle Weatherstripping as is illustrated in Figures3 and 5 is used primarily along the vertical edges of the frame and atthe top thereof for preventing passage of air currents between thedoor'10 and the frame 50. This structure is adapted to be used inconjunction with the Weatherstripping illustrated in Figures l, 2 and 4.

Since from the foregoing the construction and advantages of thisWeatherstripping construction are readily apparent, further descriptionis believed to be unnecessary.

However, since numerous modifications will readily occur to thoseskilled in the art after a consideration of the foregoing specificationand accompanying drawings, it is not intended to limit the invention tothe precise embodiment shown and described, but all suitablemodifications and equivalents may be resorted to, and obviously byreversing the position of mounting of the Weatherstripping seals can beprovided for doors which open in opposite directions.
